Title: Method and apparatus for forward link rate scheduling
Inventor: TIEDEMANN EDWARD G JR
IPC: H04B7/26
Filed: 1998-04-24
Granted: 2001-07-01
Abstract: In a communication system capable of variable rate transmission, scheduling of high speed data transmission improves utilization of the forward link and decreases the transmission delay in data communication. Each remote station is assigned one primary code channel for the duration of the communication with a cell. Secondary code channels of various types and transmission capabilities can be assigned by a channel scheduler for scheduled transmission of data traffic at high rates. Secondary code channels are assigned in accordance with a set of system goals, a list of parameters, and collected information of the status of the communication network. Secondary code channels can be grouped into sets of secondary code channels. Data is partitioned in data frames and transmitted over the primary and secondary code channels which have been assigned to the scheduled user.

Title: Telephone signals detection circuit
Inventor: HUANG BA-JUNG
IPC: H04M1/57
Filed: 1998-05-28
Granted: 2000-01-11
Abstract: A kind of telephone signals detection circuit, a circuit structure capable of distinguishing user lines reversal or ring. Adding the telephone signal signal detection circuit to usual telephone IC ring detection circuits, it would be capable of telling whether the input signal is a user line reversal signal or ring signal, thus alleviate the load on the microprocessor, and even load on the power supply. In this invention, the charging/discharging to the capacitor at telephone ring or user line reversal is utilized, a user line reversal signal and a ring signal can be distinguished by detecting the capacitor's initial discharging voltage variation and the waves occurred at charging/discharging in capacitor by means of Schimitt trigger of 2 different levels and by using a simple flip-flop. It would be possible to be immune from bounce phenomenon generated by starting the user line reversal or ring. The circuit of this invention works completely in static mode and does not have to be powered off when not working and it almost does not consume power.

Abstract: Light detection apparatus for determining the location of a body within a predetermined area comprises at least two light detection devices (10, 10', 10""), supported on the body and capable of receiving light at points which are spaced about a central axis (8). The apparatus further includes means for supplying information representative of the level of light detected by each light detecting device (10, 10', 10""). Information received from the light detection apparatus is compared with information previously received from the light detection apparatus and stored in a memory so as to identify when the light detected by the light detection apparatus is the same or substantially the same as light previously detected by the light detection apparatus. When used on an autonomous vehicle, this can allow the vehicle to determine when it has returned to a similar position in an area. The received light signal can be filtered or processed to derive information representative of different types of light (natural, incandescent) or colors of light.
